the new xports will read the bigger drives from the shop. the older versions you will need to update firmware as said above. I found it was fairly easy to use,
1)plug in USB from xport to pc
2)plug HDD into xport
3)insert software disk
4)extract data
5)copy or edit data
6)rehash/resign profile data
7) reinsert data back to HDD
for just back ups all you have to do is step 1-4 only when you mod it do you have to rehash and resign
